Dennis Baldocchi

Dennis Baldocchi is a professor of biometeorology at the University of California, Berkeley. He and his research group conduct experimental and theoretical studies on the physical, biological and chemical control of trace gas exchange between vegetation and the atmosphere. Goals of work are to predict fluxes of carbon, water and energy, mechanistically, everywhere, all of the time.

Lines of inquiry have been along understanding how fluxes of mass and energy between ecosystems and the atmosphere vary along a spectrum of time and space scales in accordance with structure, function, weather and climate and management. Methods used include use of the eddy covariance method to measure net fluxes of mass and energy across the atmosphere-ecosystem interface. Data are interpreted and distilled through the lens of the CANVEG family of models, physiological measurements at the leaf scale and flux measurements across the soil-atmosphere interface.

His current work focuses on: 1) the roles of management and ecological restoration on greenhouse gas fluxes of crops and wetlands; 2) the impact of weather, climate trends and variability, physiological stress, and structure and function on the greenhouse gas fluxes of savanna woodlands and annual grasslands; and 3) the upscaling and interpretation of fluxes across climatic and ecological gradients with the AmeriFlux and FLUXNET networks.

Prof. Baldocchi has been principal investigator of Fluxnet since 1997 and is co-investigator of Ameriflux. He is a fellow of the American Geophysical Union, recipient of the American Meteorological Society Award for Outstanding Achievement in Biometeorology and a Clarivate Analytics Highly Cited Scientist over multiple years in Agricultural Science and once in Ecology/Environment.

He served as Editor in Chief of the Journal of Geophysical Research, Biogeoscience, as subject editor of Global Change Biology and on the editorial boards of numerous other journals. He has served on numerous science advisory panels including the Max Planck Institute for Biogeochemistry and the Department of Energy, Biological and Environmental Research Division.

Dennis Baldocchi gives a keynote on Wed 12th Sept titled ‘Viewing ICOS in a global context: lessons learned from the global network, FLUXNET‘.

Mathew Williams

Mathew Williams is Chair of Global Change Ecology at the University of Edinburgh. His research is on quantifying and understanding the terrestrial carbon cycle and its links to global change. He has studied the interactions of plant and soil processes across environmental and biodiversity gradients from the tropics to the Arctic. He uses process based modelling and data assimilation methods to extract information from detailed ecosystem measurements on feedback processes between soil, vegetation and the atmosphere, over timescales from days to years. Linking to remote sensing data, his group uses models to upscale process information to investigate landscape processes. He focuses particularly on issues relating to the drought sensitivity of forests and croplands, the role of disturbance (fire or anthropogenic) on forest biomass, and the sensitivity of Arctic ecosystems to warming. Understanding and simulating the non-steady state behaviour of ecosystems is a current focal interest. Mathew is a PI for the UK National Centre for Earth Observation, Director of the NERC Field Spectroscopy Facility, a member of NERC Science Board, and on the science team for the ESA Earth Explorer Biomass Mission.
